impressions from light by various organs of vision, and towards this result you cannot but perceive that all the arrangements and motions of the planetary bodies, their satellites and atmospheres are subservient.  The spiritual natures therefore that pass from system to system in progression towards power and knowledge preserve at least this one invariable character, and their intellectual life may be said to depend more or less upon the influence of light.  As far as my knowledge extends, even in other parts of the universe the more perfect organised systems still possess this source of sensation and enjoyment; but with higher natures, finer and more ethereal kinds of matter are employed in organisation, substances that bear the same analogy to common matter that the refined or most subtle gases do to common solids and fluids.  The universe is everywhere full of life, but the modes of this life are infinitely diversified, and yet every form of it must be enjoyed and known by every spiritual nature before the consummation of all things.  You have seen the comet moving with its immense train of light through the sky; this likewise has a system supplied with living beings and their existence derives its enjoyment from the diversity of circumstances to which they are exposed; passing as it were through the infinity of space they are continually gratified by the sight of new systems and worlds, and you can imagine the unbounded nature of the circle of their knowledge.  My power extends so far as to afford you a glimpse of the nature of a cometary world.”  I was again in rapid motion, again passing with the utmost velocity through the bright blue sky, and I saw Jupiter and his satellites and Saturn and his ring behind me, and before me the sun, no longer appearing as through a blue mist but in bright and unsupportable splendour, towards which I seemed moving with the utmost velocity; in a limited sphere of vision, in a kind of red hazy light similar to that which first broke in upon me in the Colosaeum, I saw moving round me globes which appeared composed of different kinds of flame and of different colours.  In some of these globes I recognised figures which put me in mind of the human countenance, but the resemblance was so awful and unnatural that I endeavoured to withdraw my view from them.  “You are now,” said the Genius, “in a cometary system; those globes of light surrounding you are material forms, such as in one of your systems of religious faith have been attributed to seraphs; they live in that element which to you would be destruction; they communicate by powers which would convert your organised frame into ashes; they are now in the height of their enjoyment, being about to enter into the blaze of the solar atmosphere.  These beings so grand, so glorious, with functions to you incomprehensible, once belonged to the earth; their spiritual natures have risen through different stages of planetary life, leaving their dust behind them, carrying with them only their intellectual power.
